Fat grafting associated with negative pressure wound therapy.

PURPOSE: To describe a case report of FG associated with NPWT in the treatment of complex wound on the distal third of the lower limb with bone exposure. CASE REPORT: A 59-year-old patient with chronic left tibial osteomyelitis since childhood underwent extensive debridement of the distal tibial diaphysis (40% of bone thickness per 10 cm extension) and placement of bioactive glass S53P4. Distal necrosis occurred in the fasciocutaneous flap used as the primary bone coverage. After flap debridement, the case was resolved with FG, directly on the exposed bone and biomaterial, associated with NPWT. Three weeks after the first FG session over bony tissue, 100% granulation was achieved with NPWT. The closure was completed with thin laminated skin graft over the granulated wound area. DISCUSSION: The association of FG and NPWT is not known in the clinical practice. Except for the only one experimental study described by Kao et al.4, the theme was not addressed in the medical literature before. In this clinical case, the result obtained regarding the granulation tissue formation drew attention and prevented the use of more complex flaps such as the microsurgical ones. Accelerated granulation tissue formation was observed, filling an extensive and deep bone defect, even with infected bone and biomaterial. Low morbidity and no complications were observed with the use of FG associated with NPWT. When the grafted fat was compacted with the NPWT, it seemed to behave as a true autologous biological matrix with large amount of cells. To date, scientific studies on fat grafting have focused on the cellular aspect (adipocytes and mesenchymal cells), growth factors and fat differentiation in different tissues. The property of aspirated adipose tissue as a biological matrix seemed to be revealed by the application of NPWT in association with FG. This new roll for the aspirated fat tissue may represent a new research field in plastic surgery.

Lipoabdominoplastia no tratamento estético do abdome: experiência de 5 anos / Lipoabdominoplasty in the aesthic treatment of the abdomen: 5 years of experience", "_e": "n

INTRODUÇÃO: Na abdominoplastia, busca-se reduzir a flacidez e o excesso cutâneo-adiposo, melhorando curvas, cintura e relevo do abdome. Na busca por resultados estéticos mais satisfatórios, técnicas operatórias são associadas, como a lipoaspiração, na tentativa de atingir esses resultados. Este estudo teve por objetivo demonstrar a técnica cirúrgica de lipoabdominoplastia adotada pelo autor sênior ao longo de cinco anos e avaliar resultados e complicações em pacientes com indicação de abdominoplastia clássica. MÉTODO: Foi realizado estudo retrospectivo, por meio da revisão de prontuários, de um grupo de 162 pacientes submetidas a lipoabdominoplastia associada ou não a outros procedimentos, no período de maio de 2006 a maio de 2011, no Núcleo Hermínio Amorim - Cirurgia Plástica e Tratamentos Estéticos (Lavras, SP, Brasil). A idade das pacientes variou entre 33 anos e 62 anos. RESULTADOS: Em todos os casos foi observada redução significativa do tecido cutâneo-adiposo, com expressiva diminuição da flacidez abdominal e melhora do contorno corporal. A incidência de complicações pós-operatórias, como necroses, irregularidades do tecido adiposo infraumbilical, seromas, hematomas, epidermólises e deiscências, encontrada neste estudo é baixa e está de acordo com a literatura. CONCLUSÕES: A técnica de lipoabdominoplastia é um procedimento seguro, com baixo índice de complicações, desde que respeitados os critérios de segurança, que permite a obtenção de retalho bem vascularizado, com preservação das artérias perfurantes. A associação da técnica de lipoaspiração realizada no abdome e no contorno corporal é considerada segura e essencial na busca por melhor harmonia corporal, por melhores resultados estéticos e, consequentemente, por maior satisfação do paciente.

BACKGROUND: Abdominoplasty aims to reduce saggy skin and excessive skin and adipose tissue, as well as to improve curves, the shape of the waist, and the volume of the abdomen. In order to enhance aesthetic results, additional operative techniques such as liposuction are associated with abdominoplasty. This study aims to demonstrate the surgical technique of lipoabdominoplasty used by the senior author during a period of 5 years, and evaluate the results and complications in patients with indication for classic abdominoplasty. METHODS: We performed a retrospective study using medical records from a group of 162 patients who underwent lipoabdominoplasty associated with other procedures or not, from May 2006 to May 2011. The age of the patients ranged from 33 to 62 years. RESULTS: In all cases, we achieved significant reduction of skin and adipose tissue, together with a decrease in amount of saggy skin and improvement in body shape. The incidence of postoperative complications such as necrosis, irregularities in the infraumbilical adipose tissue, seromas, hematomas, epidermolysis, and dehiscence in this study was low, similar to the literature findings. CONCLUSIONS: Lipoabdominoplasty is a safe procedure, and has low complication rates when the safety criteria that permit a well-vascularized flap with preservation of the perforant arteries are followed. Association of lipoabdominoplasty with liposuction in the abdominal area and body shaping is considered safe and essential when seeking better body harmonization and aesthetic results, which results in improved patient satisfaction.
